(a) The distance required to take off and climb over a 50-foot obstacle shall be determined under the following conditions:
(1) Most unfavorable combination of weight and center of gravity location, (2) Engines operating within the approved limitations, (3) Cowl flaps in the position normally used for take-off.
(b) Upon obtaining a height of 50 feet above the level take-off surface, the airplane shall have attained a speed of not less than 1.3 Vs1 unless a lower speed of not less than Vx plus 5 can be shown to be safe under all conditions, including turbulence and complete engine failure.
(c) The distance so obtained, the type of surface from which made, and the pertinent information with respect to the cowl flap position, the use of flight-path control devices and landing gear retraction system shall be entered in the Airplane Flight Manual. The take-off shall be made in such a manner that its reproduction shall not require an exceptional degree of skill on the part of the pilot or exceptionally favorable conditions. CLIMB
